The Victron Energy MultiPlus-II GX 48/6k5/100-50 is a multifunctional inverter/charger designed for 48V battery systems. It combines a sine wave inverter, a battery charger and a GX device for system monitoring and control in a single enclosure.
With a continuous output power of 6kW at 25°C and a peak power of up to 11kW, the unit can support residential loads, off-grid installations, mobile systems and professional applications. The built-in charger can deliver up to 100A, depending on the operating temperature and system configuration.
In the event of a grid outage or generator disconnection, the MultiPlus-II GX automatically switches to battery power. The main AC output can continue supplying critical loads, while the 32A auxiliary output is intended for equipment that should operate only when an AC source is available.
Integrated GX monitoring
The built-in GX device simplifies system integration and monitoring. Battery, inverter and compatible solar charge controller parameters can be viewed locally on the two-line display or remotely through the Victron Remote Management platform – VRM.
The system can be connected to the network via Wi-Fi or Ethernet and provides USB, VE.Direct and BMS-CAN interfaces for integrating compatible equipment.
PowerControl and PowerAssist
The PowerControl function allows a limit to be set for the current drawn from the grid or generator. When the installation’s power consumption increases, the MultiPlus-II GX can automatically reduce the current used for battery charging, helping prevent the AC source from being overloaded.
With PowerAssist, energy stored in the batteries can temporarily supplement the power available from the grid or generator. Once consumption decreases, the available surplus is used to recharge the batteries.
Expandable configurations
Multiple MultiPlus-II units can be configured in parallel to increase system output power and charging capacity. The product can also be used in three-phase installations. Only one unit with GX functionality is required in a parallel or three-phase system.

Battery compatibility
The MultiPlus-II GX can be configured for lithium, lead-acid, zinc-bromine and other compatible battery technologies. The charger parameters must be configured according to the battery manufacturer’s requirements.
For CAN-managed batteries, the BMS-CAN port is intended for compatible models that communicate at 500kbps. It should not be confused with a standard VE.Can port.
Compatibility depends on the battery model, BMS protocol and firmware version. We recommend checking the system configuration before purchase.
Protections
The product includes protection against:
- Output short circuit
- Overload
- Excessively high battery voltage
- Excessively low battery voltage
- Excessive temperature
